High Court papers have allegedly been obtained by The Mirror, which state that Rihanna was not happy with how she looked on the clothing ranges.

It reads: "The base image of the first claimant [Rihanna] is of such an unflattering nature that it would not be approved."

The shirts - which bore the image of Rihanna with her hair in a bandana - were also branded "poor" quality.

They are described as having a "low-quality image and product that would not have been authorised by the first claimant".

However, there is reportedly no figure stated in the papers, despite claims of her seeking £3.5 million.

Rihanna - who has already spent $1 million pursuing the case - is believed to be moving ahead with legal proceedings out of principle rather than for financial gain.

She recently unveiled her summer fashion range for River Island. The collection is her second for the UK high street brand and also includes various items bearing her face.
